"All bombing plots in Iran have failed and all the terrorist groups that intended to do so have been prevented from crossing the country's borders," Zolfaqari told reporters on the sidelines of a security meeting in the city of Mashhad, Northeastern Iran.

He reiterated that all terrorist activities of the Takfiri groups have been fully defused over the past two years, and said, "The country's security forces have brought sabotage attempts to the Zero level in border regions."

"The ISIL is too small to threaten us," Pourdastan told reporters in Tehran on Monday.

He also announced that the anti-terrorism drills which were due to be staged on the outskirts of Tehran city today were postponed to mid January, adding that they will be held near the Central city of Qom more extensively and with higher quality.

In relevant remarks last Wednesday, a senior Iranian commander announced that the country's Ground Forces had planned and prepared themselves for holding several massive wargames in the next few months.

"We have provided the ground for a number of drills in the near future, which will be staged by the end of the current (Iranian) year and people will be informed about their details (later)," Lieutenant Commander of the Iranian Ground Force Brigadier General Kioumars Heidari told FNA.

He also underlined the Iranian Armed Forces' preparedness to confront any aggression, and said the terrorist groups, including the ISIL, and their allies are unable to pose a threat to the Iranian borders and even the superpowers are not able to make military aggression against the country.
